This past Monday, I was covering a shift for a full time employee as I am only part time on our sort. My shift I was covering for the peak season was from 8:30 a.m. until 11:30 p.m. that was including doing their job and then working on my sort as well, whenever I was finished doing their job and I was getting ready to start our sort I had asked if I could take a 15 minute break to get food. My supervisor had replied that I was just covering a full time employee so I did not get a break, so if I'm not mistaken if I was to work the hours that I did I should at least have gotten a one hour lunch and one or two breaks for 15 minutes thanks to OSHA. I was talking to some of the other employees that day and they said that they agree that I should have gotten a break and they told me to file a grievance. One of the other supervisors had overheard the conversation I guess and had told me that the next day since I'm covering the shift all week that I can take me a lunch for 1 hour everyday all I have to do was ask but when I had asked they said that I didn't get a break or lunch. So were they just telling me that so they wouldn't get in trouble? What can I do about the situation? And it's not like I'm making overtime because they're making me work the full time job just long enough that I don't make over time doing that and that screws me out of overtime on my sort. Would there be a benefit to a grievance if so what would it be and is it worth the hassle that would come?
